Embodiment

The present invention is further detailed explanation below in conjunction with accompanying drawing.

Mainly fixedly journal stirrup 14, transition feet 15, base plate 16, exit 17, control terminals 18, lead-out wires of coil 19, coil exit 20, metal substrate 21, through hole 22 and glass insulator 23 form a kind of novel wind-speed relay of the present invention by temperature relay 1, heater 2, metal base 3, bracing frame 4, outer cover 5, bimetallic element 6, pressing plate 7, dividing plate 8, die cavity 9, heater strip 10, interior insulating trip 11, external insulation sheet 12, heating plate 13, U-shaped.

As shown in Figure 3 and Figure 4, described heater 2 by the U-shaped at temperature relay 1 upper bracket top fixedly journal stirrup 14 be connected and fixed, temperature relay 1 is fixedly connected with metal base 3 by spot welding by bracing frame 4.The coil exit 20 of temperature relay 1 exit 17 and heater 2 is connected with the lead end on metal base 3 respectively.

As shown in Figure 3, the bimetallic element 6 of described temperature relay 1 is arranged in the die cavity 9 by bracing frame 4, pressing plate 7 and dividing plate 8 besieged cities.Heater strip 10 is spirally wound on interior insulating trip 11, pads respectively up and down lastblock external insulation sheet 12, by after heating plate 13 parcels, forming heater 2.The bimetallic element 6 of 2 pairs of temperature relays 1 of heater heats, by adjusting operating temperature point and the recovery temperature point of bimetallic element 6, guarantee the requirement of air flow relay different action air speed value and reply air speed value, thereby solved the unsettled problem of action air speed value.
